UNITED STATES PATENT QFFICE SAMUEL M. MARSDEN, OF WILKESBARRE, PENNSYLVANIA.

IMPROVEMENT IN WASH-BOILERS.

Specification forming part of Letters Patent No. 159,196, dated January 26,1875; application filed March 20, 1874.

To all whom it may concern: Y

Be it known that I, SAMUEL M. MARsDEN, of Wilkesbarre, Luzerne county, State of Penn sylvania, have invented certain Improvements in Steam Washing and Drenching Boilers, of which the following is a specification:

The object of my invention is so to apply steam and boiling water to the washing and drenching clothes that the work may be done and the waste-water removed, and no interruption, that heavy lifting and danger from scalding water may be avoided, and a machine constructed easy to manage, and easily kept in repair, as will more fully appear from the accompanying drawings.

Figure 1 is an elevation view of a common wash-boiler, with faucets, filter, flange, portable and supply pipes. Fig. 2 is a transverse sectional view of the same. Fig. 3 is a longitudinal sectional view of the same, showing the water and steam chambers. Fig. 4 is an elevation view of an ordinary hot-water tank, usually connected with kitchen-ranges, with pipes leading to the boiler and range.

A, Figs. 1 and 2, is a common washboiler, constructed in the usual form, of common ma terials, the bottom fiat, fitted to be placed on any common support, or made a kitchen fixture.

A, Figs. 1, 2, and 3, is a flange of the same material as the boiler, siX to eight inches wide, soldered to the upper edge of the boiler, inclining moderately outward.

A, Figs. 2 and 3, is a movable metallic bottom, snugly fitted to the inside of the boiler, with a narrow flange, a a, siX inches wide, or therea-bout, on which it stands.

B, Figs. 2 and 3, is a water-chamber, formed by and between movable bottom A, last described, and the bottom of the boiler A. This water chamber receives the waste water, whence it is drawn off at will. To facilitate this discharge of waste-water the flange a ais pierced by holes a a, Fig. 3, directly opposite, and leading into faucets G G B B, Figs. 2 and 3, are two steam-chambers, set upon either end, and made part of the movable bottom A. That side of the chambers next the inner surface of the boiler is conformed to that surface. The inner surface of the chambers, making part of the inr side of the boiler, when arranged for work, is straight. These chambers extend to within about six inches of the upper edge of the boiler, and their upper ends, I) b, are flat, on which rests the filter O, or whatever serves as a cover to the boiler. The width or diameter of the lower ends of these chambers is from six to eight inches, slightly tapering to the upper ends. The inside, and near the upper ends, the chambers are perforated by several small holes, I) b, Fig. 2, whereby steam or boiling water may be thrown over the articles to be cleansed.

13, Figs. 2 and 3, is a metallic valve, located beneath an orifice cut from the center of the movable bottom A, two inches, or thereabout, in diameter, protected from above by a metallic stationary cap, (1. This valve is suspended on an axle, b 1), Figs. 2 and 3, held in a perpendicular position by two metallic straps, c c, bent over said orifice above and below. This valve is, first, to permit steam from the chamber B to penetrate the overlying clothes, and, second, the escape of Wastewater thence out.

(J, Figs. 2 and 3, is an oblong metallic filter, its height about one-third its length, serving as a cover to the boiler A, resting on the upper ends of the steam'chamber B B, as above. six inches inward from the lower edge or rim, is dropped, forming shoulders c 0, Figs. 2 and 3, about two inches deep. The under surface 0 0, same figures, is thickly perforated with small holes, designed to thoroughly distribute steam or water from the hot-water tank E, Fig. 4, next described.

E, Fig. 4, is a common metallic hot-water tank, such as is usually connected with kitchenranges, as in thiscase by pipe F. The tank communicates with the upper part of the boiler A by the pipe E, and with the lower part or water-chamber B by pipe Gr, same figure.

H S S E are common metallic faucets, attached, respectively, to the pipes G and E, Figs. 1 and 4, said pipes jointed at g and g, and fitted to each other by tenons and sockets, for convenience. Faucet-s H and G, with their pipes, being set at the bottom of boiler A, but on different sides, and communicating The under surface, commencing about directly with the water-chamber B, as seen in Figs. 2 and 3, by means of holes a a through the flange a a, serve to thoroughly cleanse the chamber B and the entire boiler without disarran gin g its interior, by driving water through pipe G, or in through either of said faucets, and out of the other.

F, Figs. 1, 2, and 3, is a movable metallic tube, open at both ends, set perpendicularly through the upper, and resting on the perforated inner, surface of the filter O, fitting as closely as practicable to the orifice through which it passes, and communicating with said filter by the perforations f f through the lower end of said tube, designed to prevent any dangerous accumulation of steam.

F, Figs 2 and 3, is a common metallic tube,

open at both ends, firmly fitted into the movable bottom A perpendicularly, and covered with a removable cap. This tube, passing through said bottom, having a' diameter of three or four inches, and reaching nearly to the bottom of the filter O, is for the purpose of conveying soap to the Waterchamber B.

I claim- The Water-chamber B, steam-chamber B, movable bottom A tube F, in combination with valve B, as constructed, substantially as and for the purpose set forth.
